Bullet Audyssey is a music-based arcade shooter in which you will face gigantic enemies and bullet hell scenarios. Your enemies' shooting patterns are in sync with the beat. The bullets are in the form of red orbs and contain energy, which you must collect to power your own attacks. Collect energy by touching the red orbs with your ship's pulsating aura, but be careful not to touch them with the ship itself. Your energy can be used to shoot bullets and temporarily slow down time. Complete levels to earn rewards that will improve your ship.
